Because we are at a loss as to what to do with these people. The war on drugs has failed and more and more people are doing straight up crazy s^*$ because of stuff like this. I think a charge of animal cruelty is letting this guy off easy. He should be required to be hospitalized and undergo a mental evaluation, at the least.

The "zombie" thing is, I think, because people struggle with the feeling of helplessness at the craziness of the world these days. It's a coping mechanism.
